[0049] The following is attached to the instruction manual Figure 1-Figure 11 The grease corrosion protection tester of the present invention is described.

[0050] Embodiment 1:

[0051] like Figure 1 , Figure 2 , Figure 7 , Fig. 9 and Fig.11 As shown, in one embodiment, a grease corrosion resistance tester includes a housing 100, and a driving member 200, a supporting member 300, an injection mechanism 400, and a mixing mechanism 500 disposed inside the housing 100; wherein:

[0054] The support member 300 is fixedly installed in the box body 100 through a positioning column, and includes two clamping rings 310 symmetrically arranged up and down;

[0055] The injection mechanism 400 is provided with four and is installed on the clamp ring 310, including an arc-shaped sponge 410, a strip sponge 420 and a guide ring 430. The arc-shaped sponge 410 is installed on the clamp ring 310, and one end of the strip sponge 420 passes through the guide ring 430 and is fixedly connected to the guide ring 430;

[0056] There are two adjusting mechanisms 500, which are symmetrically installed between the two retaining rings 310, including two adjusting rings 510 fixedly installed on the upper and lower sides of the guide ring 430 respectively, and two annular guide grooves 511 are provided on the inner side of the adjusting ring 510, and two strip guide grooves 512 connected to the annular guide grooves 511 are provided on the inner side of the adjusting ring 510.

[0058] It should be noted that, in this embodiment, by adopting the above-mentioned trumpet-shaped equalizing ring 510, the grease accumulated between the guide ring 430 and the inner ring can be swung outward by the centrifugal force during the rotation of the inner ring. Combined with the shape of the inner side of the equalizing ring 510, the grease diffuses to the upper and lower sides of the guide ring 430. During the diffusion process, part of the grease is squeezed into the corresponding annular guide groove 511 to complete the lateral diffusion. At the same time, during the rotation of the inner ring, the grease on the outer side can be dropped to different positions on the equalizing ring 510. area to increase the speed of grease layer formation; at the same time, after the strip sponge 420 continuously introduces grease, the continuously rotating inner ring allows the grease to continue to diffuse, and eventually, the gaps between the guide ring 430, the mixing ring 510 and the inner ring will be filled, thereby forming a grease layer of a certain thickness, achieving a stable and uniform grease injection effect. At the same time, the arc sponge 410 can inject grease into the ball alone, and use a wrapping and smearing method to complete a comprehensive grease coating operation during the continuous rotation of the ball to ensure uniformity.

[0059] As a preferred embodiment, Figure 6 , Fig. 9 and Fig.11 As shown, two cover plates 513 are hinged inside the strip-shaped guide groove 512, and the opposite sides of the two cover plates 513 are both arranged at angles.

[0060] Specifically, in this embodiment, by adopting the angle setting on the cover plate 513, the grease can be assisted in the diversion operation, which is convenient for helping the grease to move into the corresponding annular guide groove 511 to ensure the diffusion effect of the grease.

[0061] As a preferred embodiment, Fig. 9 and Fig.11 As shown, a first spring 514 is installed between the cover plate 513 and the strip guide groove 512, a piston bar 517 is slidably connected to the inside of the adjusting ring 510, one side of the piston bar 517 is fixedly connected to the outer side of the cover plate 513 by a pull rope 518, two through holes are opened inside the strip guide groove 512, a circular plate 515 is hinged inside the through hole, and a second spring 516 is installed between one side of the circular plate 515 and the through hole.

[0062] Specifically, in the present embodiment, through the arrangement of the above-mentioned structure, before the ball bearing needs to be removed for inspection, the piston bar 517 can be driven to move, so that it drives the pull rope 518 to pull the cover plate 513, so that the side of the cover plate 513 moves toward the outside of the inner ring, thereby scraping the grease layer on the inner ring, and introducing the grease along the cover plate 513 into the strip guide groove 512, and then the negative pressure in the three-way pipe is used to make the circular plate 515 hinged to move, so that the scraped grease is introduced into the collection box 314 along the through hole.

[0063] Embodiment 2:

[0064] Different from the above-mentioned embodiment 1, Figure 2 and Figure 6 As shown, the injection mechanism 400 also includes an electric grease nozzle 440, and the output end of the electric grease nozzle 440 is connected to two conduits, one end of the two conduits respectively extends to the inside of the arc sponge 410 and the strip sponge 420, and installation boxes are sleeved on the outside of the arc sponge 410 and the strip sponge 420, the two installation boxes are fixedly connected on opposite sides, and the outer installation box is embedded in the clamping ring 310.

[0065] It should be noted that in this embodiment, through the setting of the above-mentioned structure, when grease introduction is required, the feed pipe on the electric grease nozzle 440 can be connected to the grease pipeline, and then started to inject the grease into the interior of the arc sponge 410 and the strip sponge 420 along the corresponding conduits.

[0066] As a preferred embodiment, Figure 2 , Figure 3 and Figure 6As shown, an electric push rod 311 is provided on the outside of the retaining ring 310, and a piston plate 312 is installed on one end of the electric push rod 311. A collecting tube 313 located on the outside of the retaining ring 310 is installed on the outside of the electric push rod 311. Two collecting boxes 314 are provided on the outside of the collecting tube 313. The collecting boxes 314 are arranged on the outside of the mixing ring 510 and are connected with the through hole. A three-way pipe is threadedly connected to the collecting tube 313, and one end of the three-way pipe is connected with the collecting box 314.

[0067] Specifically, in this embodiment, the electric push rod 311 is started to drive the piston plate 312 to move in the collection tube 313. At this time, the three-way pipe on the collection tube 313 will perform a vacuum operation, thereby forming a negative pressure inside the collection box 314, and the circular hole is used to perform a grease recovery operation.

[0068] Embodiment 3:

[0069] Different from the above embodiment, Figure 2 As shown, the driving member 200 includes a speed regulating motor 210, a connecting disk 230 and a group of anti-slip bars 220 evenly distributed on the connecting disk 230. The speed regulating motor 210 is installed on the inner bottom wall of the box body 100. The output shaft of the speed regulating motor 210 is fixedly connected to the connecting disk 230 through a coupling, and a group of hydraulic rods fixedly connected to the anti-slip bars 220 are arranged inside the connecting disk 230.

[0070] It should be noted that in this embodiment, through the setting of the above-mentioned structure, after the ball bearing is placed, the hydraulic rod can be started to drive the anti-slip rod 220 to move outward until it is in tight contact with the inner wall of the inner ring of the ball bearing, and then the speed regulating motor 210 is started, and different speeds are selected according to the test requirements to drive the ball bearing injected with grease to move.

[0071] Embodiment 4:

[0072] Different from the above embodiment, Figure 2 and Figure 7 As shown, the support member 300 also includes two electric lifting rods 320, which are installed inside the bottom clamping ring 310, and the top ends of the electric lifting rods 320 are fixedly connected to the top clamping ring 310, and the bottom clamping ring 310 is fixedly installed inside the box body 100.

[0073] It should be noted that in this embodiment, through the setting of the above-mentioned structure, before conducting a test, the electric lifting rod 320 can be started to drive the top retaining ring 310 to move upward, thereby facilitating the user to place the ball bearing. The same steps are also used when taking it out later, which facilitates the user to take out and place the ball bearing.

[0074] Embodiment 5:

[0075] Different from the above embodiment, Figure 1 , Figure 2 and Figure 3 As shown, a vertical pipe 110 is installed inside the box body 100, a heating wire 120 is arranged inside the vertical pipe 110, and a group of discharge holes are opened on the outside of the vertical pipe 110, and a horizontal pipe 130 extending to the inside of the bottom clamp ring 310 is installed on the outside of the vertical pipe 110, and a metal ring 315 is fixedly installed inside the bottom clamp ring 310, one end of the metal ring 315 extends to the inside of the top clamp ring 310, and one end of the horizontal pipe 130 is close to the metal ring 315.

[0076] It should be noted that, in this embodiment, the staff can operate the heating wire 120, and use a single-chip microcomputer and a PID controller to regulate the temperature of the heating wire 120; the discharge hole is used to introduce the heat energy in the riser 110 into the box body 100 to complete the test operation of the corrosion resistance of the grease under different temperature environments.

[0077] At the same time, after the normal temperature control test is completed, the staff can place a new ball bearing, open the valve on the cross pipe 130, and directly introduce the heat source into the metal ring 315. The metal ring 315 in contact with the outer ring of the ball bearing can quickly increase the temperature of the ball bearing, thereby simulating the instantaneous high temperature of the engine and the overload of the electromechanical equipment, so as to test the corrosiveness of the grease under short-term high temperature conditions.

[0078] As a preferred embodiment, Figure 4 , Figure 8 and Fig. 9 As shown, a material guiding channel is formed between the strip guide groove 512 , the annular guide groove 511 and the cover plate 513 , and the arc-shaped sponge 410 and the strip sponge 420 are both made of polytetrafluoroethylene sponge.

[0079] Specifically, in the present embodiment, through the arrangement of the above-mentioned structure, when the amount of grease injected is too much, a grease layer of a certain thickness is formed between the guide ring 430, the mixing ring 510 and the inner ring, and the excess grease can move along the material guide channel to between the cover plate 513 and the circular plate 515, and then, when too much grease is introduced, it moves along the through hole and squeezes the circular plate 515, so that the excess grease is placed inside the through hole and introduced into the collection box 314, thereby playing an anti-overflow effect in the process of grease mixing, reducing the phenomenon of grease being randomly thrown out and accumulated on the side of the ball bearing.

[0080] The working principle and use process of the grease corrosion resistance tester of the present invention include: before the test, the electric lifting rod 320 can be started to drive the top retaining ring 310 to move upward, so that the user can place the ball bearing, and then the two retaining rings 310 are merged to complete the limiting of the ball bearing, so that the outer ring is clamped by the two retaining rings 310, and the inner ring can move normally, and then the speed regulating motor 210 is used to drive the inner ring to rotate. During the rotation process, the electric grease nozzle 440 is started to inject the grease into the arc sponge 410 and the strip sponge 420 along the corresponding conduit. At this time, part of the grease is on the outside of the ball, and part of the grease is between the guide ring 430 and the inner ring. During the rotation of the inner ring, the centrifugal force drives the grease to swing outward, and matches the shape of the inner side of the mixing ring 510. The grease is diffused longitudinally on the upper and lower sides of the guide ring 430. During the longitudinal diffusion process, part of the grease is squeezed into the corresponding annular guide groove 511 to complete the lateral diffusion. At the same time, during the rotation of the inner ring, the grease on the outer side can be dropped to different areas on the mixing ring 510 to increase the speed of the grease layer formation. After the strip sponge 420 continuously introduces the grease, the grease is continuously diffused with the continuously rotating inner ring. Finally, the gaps between the guide ring 430, the mixing ring 510 and the inner ring will be filled, thereby forming a grease layer of a certain thickness, achieving a stable and uniform grease injection effect. At the same time, the arc sponge 410 can inject grease into the ball alone, and complete the comprehensive grease coating operation during the continuous rotation of the ball by wrapping and smearing to ensure uniformity.

[0081] In the process of grease injection, if an excessive amount of grease is injected, the excess grease can move along the material guide channel to between the cover plate 513 and the circular plate 515, and then move along the through hole and squeeze the circular plate 515 when the introduced grease is excessive, so that the excess grease is placed inside the through hole and introduced into the collection box 314, thereby preventing overflow during the grease mixing process and reducing the phenomenon of grease being thrown out randomly and accumulating on the side of the ball bearing.

[0082] When the ball bearing needs to be removed for inspection, the pull rope 518 pulls the cover plate 513 to move the side of the cover plate 513 toward the outside of the inner ring, thereby scraping the grease layer on the inner ring and introducing the grease into the strip guide groove 512 along the cover plate 513. Then, the negative pressure in the three-way pipe is used to make the circular plate 515 hinged to introduce the scraped grease into the collection box 314 along the through hole, thereby reducing the phenomenon of excessive grease remaining on the inner ring, making it easier for staff to take and inspect, and at the same time achieving the effect of grease recycling and energy saving.

[0083] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0084] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
